ABSTRACT

Objetivo: Determinar a prevalência de lesões cervicais não cariosas em crianças na dentição decídua e possíveis fatores etiológicos associados. Métodos:Após a aprovação do Comitê de Ética ­ CEP/UESPI (3.289.732), o estudo transversal foi realizado em 360 crianças com idade entre 2 a 6 anos, de escolas públicas e privadas, divididas em dois grupos: G1 (com lesões cervicais) e G2 (sem lesões cervicais). Foi aplicado um questionário aos pais, seguido do exame clínico das crianças. Foram consideradas lesões detectadas pelo tato e visualmente. Foram realizadas avaliações das médias e dos desvios padrão para variáveis quantitativas. Obteve-se porcentagens e frequências, realizando-se análises de associação entre as variáveis qualitativas a partir do qui-quadrado e comparação da idade média a partir do teste t (p < 0,05). Resultados: Somente lesões do tipo abfração foram encontradas na amostra (5%) e os indivíduos de raça branca apresentaram uma maior prevalência em relação aos demais (55,5%). Houve diferença estatisticamente significativa (p < 0,001) e essas lesões foram identificadas somente em escolas privadas. Quanto ao sexo, em G1, houve diferença estatisticamente significativa, (p = 0,01) com maior prevalência no masculino (66,7%). Os dentes mais acometidos em ordem decrescente foram os caninos e incisivos centrais superiores seguidos dos caninos e incisivos centrais inferiores. Conclusão: A prevalência de lesões cervicais não cariosas, do tipo abfração, em crianças de 2 a 6 anos de idade foi de 5%, tendo sido encontradas somente em escolas privadas, com predominância no sexo masculino. Houve associação entre a abfração e o tipo de escova utilizada na escovação dentária, apresentando maior frequência de lesões quando escovas duras eram utilizadas e escovação forte era executada.


Aim:To determine the prevalence of non-carious cervical lesions in children in the primary dentition and possible associated etiological factors. Method: After approval by the Ethics Committee - CEP / UESPI (3,289,732) ­ this cross-sectional study was carried out on 360 children, from 2 to 6 years of age, from public and private schools, divided into two groups: G1 (with cervical lesions) and G2 (without cervical lesions). A questionnaire was applied to the parents, followed by the children's clinical examination. Lesions detected by touch and visually were considered. Evaluations of means and standard deviations were performed for quantitative variables. Percentages and frequencies were obtained, analyzing the association between qualitative variables based on the chi-square test and comparing the average age using the t test (p < 0.05). Results:Only abfraction-type lesions were found in the sample (5%), and white individuals presented a higher prevalence in relation to the others (55.5%). There was a statistically significant difference (p < 0.001), and these lesions were found only in private schools. As for sex, in G1, there was a statistically significant difference (p = 0.01) with a higher prevalence in males (66.7%). The most affected teeth in decreasing order were the canines and upper central incisors, followed by the canines and lower central incisors. Conclusion: The prevalence of non-carious cervical lesions of the abfraction type in children from 2 to 6 years of age was 5%, which was only found in private schools, with a predominance in males. An association was found between the abfraction and the type of brush used in toothbrushing, with a higher frequency of lesions when hard brushes were used and strong brushing was performed.

ABSTRACT

Tracheal rupture is an infrequent complication with high morbidity and mortality, of multifactorial etiology, being orotracheal intubation its main cause. Spontaneous tracheal rupture usually occurs after severe coughing and/or vomiting over a weakened trachea. The diagnosis is non-specific, based on highly suggestive signs and symptoms such as subcutaneous emphysema, pneumomediastinum and respiratory distress, and its confirmation requires the performance of a bronchoscopy. The location and extent of the rupture determines the clinic. This implies the importance of an early diagnosis to avoid a poor prognosis. We present the case of an elderly male patient with a spontaneous tracheal rupture without apparent cause


La rotura traqueal es una complicación infrecuente de etiología multifactorial, con una elevada morbimortalidad, la intubación orotraqueal es su principal causa. La rotura traqueal espontánea suele producirse luego de toser o presentar vómitos intensos, sobre una tráquea debilitada. El diagnóstico es inespecífico, se basa en signos y síntomas altamente sugestivos como enfisema subcutáneo, neumomediastínico y dificultad respiratoria y su confirmación exige la realización de una broncoscopia. La localización y extensión de la rotura determinan la clínica. Esto implica la importancia del diagnóstico precoz para evitar un pronóstico infausto. Se presenta el caso de un paciente varón, de edad avanzada. con una rotura espontánea traqueal sin causa aparente

ABSTRACT

RESUMEN Las asfixias mecánicas son aquellas que resultan del impedimento mecánico a la penetración del aire en las vías respiratorias, suelen clasificarse atendiendo a la naturaleza del medio mecánico que las origina y a su modo de actuar. La estrangulación puede definirse como la constricción del cuello mediante la aplicación de una fuerza activa, ajena al peso del cuerpo, que actúa por intermedio de un lazo, las manos, el antebrazo o cualquier otra estructura rígida. En la estrangulación antebraquial, la constricción del cuello se lleva a cabo normalmente rodeando al individuo con el brazo y el antebrazo. Cuando el mecanismo de la compresión del cuello es lateral, no se afectan las vías aéreas, la compresión de las arterias carótidas hace que se produzca una isquemia cerebral y pérdida de conocimiento en 10-15 segundos. El mecanismo de muerte en estos casos será la anoxia cefálica. Si la compresión del cuello es anterior, actúa ocluyendo las vías aéreas, la presión sobre los cartílagos tiroides y cricoides puede producir fracturas y el mecanismo de muerte será la obstrucción respiratoria. El presente trabajo constituyó un caso poco común de estrangulación, donde se utilizó un mecanismo combinado que llevó al occiso al deceso final. Para la realización de la discusión del caso se tuvo en cuenta los elementos del lugar del hecho, el examen del exterior y el interior del cadáver (AU).


ABSTRACT Mechanical asphyxias are those resulting from the mechanical obstruction of the air penetration in the airways. They are usually classified according to the nature of the mechanical mean producing it and the way it performs. Strangulation may be defined as neck constriction through the application of an active force not proper to the body weight, acting by means of a knot, hands, forearm or any stiff structure. In ante brachial strangulation, neck constriction is normally performed surrounding the individual with the arm and forearm. When the neck constriction mechanism is lateral, the airways are not affected: carotid arteries constriction produces a brain stroke and loss of consciousness in 10-15 s. The death mechanism in these cases will be cephalic anoxia. If the neck compression is anterior, it occludes the airways; the pressure on thyroidal and cricoid cartilages may produce fractures and death mechanism will be respiratory obstruction. The current work deals with an uncommon strangulation case, where a combined mechanism led the person to the final decease. For the case discussion the authors took into account the elements of the place, and the examination of the exterior and the inside of the corpse (AU).

ABSTRACT

ABSTRACT Non-Carious Cervical Lesions (NCCL) are a current problem of multifactorial origin that is associated with the loss of vertical occlusal dimension, hypersensitivity, loss of teeth, fractures, and many other pathologies that affect the masticatory function of the oral cavity. Identification of the etiological factors of NCCL comprises a key piece for the solution of the problem. Based on clinical scientific evidence related with the diagnosis, a restorative treatment must be planned according to the loss of dental structure in order to return function and aesthetics. The purpose of this case report was to describe a 54-year-old male patient who was diagnosed with generalized NCCL combined with occlusal vertical dimension loss. The protocol of the treatment process is described.


RESUMEN Las lesiones cervicales no cariosas (LCNC) son una problemática actual de origen multifactorial, la cual se ve asociada a la pérdida de dimensión vertical oclusal, hipersensibilidad, pérdida de dientes, fracturas y muchas otras patologías que afectan la función masticatoria de la cavidad bucal. La identificación de los factores etiológicos de las LCNC son piezas claves para la solución del problema. Basados en la evidencia científica clínica relacionado con el diagnóstico, se debe planificar un plan de tratamiento restaurativo que depende de la pérdida de la estructura dentaria para devolver la función y estética. El objetivo de este reporte de caso es describir a un paciente masculino de 54 años a quien se le diagnosticó LCNC generalizadas combinado con una pérdida de dimensión vertical oclusal. El protocolo de plan de tratamiento es descrito paso a paso.

ABSTRACT

RESUMEN Los traumatismos en cuello se pueden clasificar las lesiones en contusas y penetrantes, en el caso de las heridas penetrantes las ocasionadas por arma punzocortante son las más frecuentes. Las manifestaciones clínicas dependen del mecanismo del trauma, tamaño y nivel de la lesión. Paciente masculino de 26 años de edad con heridas por arma punzocortante en cuello y muñecas se ingresó a quirófano de urgencia, se realizó una exploración vascular de cuello encontrando una avulsión completa del ligamento cricotiroideo, se realizó la reparación del defecto con un colgajo de los músculos cricotiroideos, cursando una buena evolución es egresado al duodécimo día. El diagnóstico de las lesiones traqueales es desafiante y debe realizase rápidamente. Se debe instalar una vía aérea definitiva de manera eficaz y planear la reconstrucción quirúrgica. El seguimiento postoperatorio realizado de manera interdisciplinaria es esencial para el pronóstico(AU)


ABSTRACT Neck injuries can be classified as blunt or penetrating injuries. Penetrating injuries caused by a puncturing gun are the most frequent. The clinical manifestations depend on trauma mechanism, and on lesion size and degree. We present the case of a 26-year-old male patient with puncture injuries to the neck and wrists. After he was admitted to the emergency room, a vascular exploration of the neck was performed, finding a complete avulsion of the cricothyroid ligament. The defect was repaired with a flap of the cricothyroid muscles. The patient had a good evolution and was discharged on the twelfth day. The diagnosis of tracheal lesions is challenging and must be carried out quickly. A definitive airway should be installed efficiently, as well as the planning of the surgical reconstruction. The postoperative follow-up performed in an interdisciplinary way is essential for the prognosis(AU)

ABSTRACT

OBJECTIVE@#To explore and compare the safety depths of perpendicular and oblique acupuncture at Yamen (GV 15) in patients with atlantoaxial dislocation (AAD) and healthy volunteers.@*METHODS@#One bundred and seventy-seven patients with atlantoaxial dislocation were selected as an AAD group, and 207 patients without atlantoaxial dislocation and with normal anatomical structure were selected as a normal group. All participants were moderately sized. The MRI scanning of the cervical vertebra was performed, and the safety depth of perpendicular and oblique acupuncture at Yamen (GV 15) was calculated on the sagittal image.@*RESULTS@#In the AAD group, the safety depth of men was (45.33±5.17) mm for perpendicular acupuncture and (48.58±4.41) mm for oblique acupuncture; the safety depth of women was (44.17±7.80) mm for perpendicular acupuncture and (47.49±7.32) mm for oblique acupuncture. In the normal group, the safety depth of men was (47.72±5.06) mm for perpendicular acupuncture and (42.69±5.53) mm for oblique acupuncture; the safety depth of women was (44.63±5.85) mm for perpendicular acupuncture and (39.88±6.18) mm for oblique acupuncture. The safety depth of men and women for oblique acupuncture was longer than that for perpendicular acupuncture in the AAD group (0.05); the safety depth of perpendicular and oblique acupuncture for men was longer than that for women in the normal group (0.05), while the safety depth of oblique acupuncture in the AAD group was longer than that in the normal group (<0.01).@*CONCLUSION@#The safe depth of acupuncture at Yamen (GV 15) has significantly changed under AAD, so during the clinical acupuncture the needle insertion should be less than its safe depth.

ABSTRACT

Objective: The prevalence of non-carious cervical lesions (NCCLs) has increased in the recent years, especially in the elderly population. The successful prevention and treatment of those lesions requires an understanding of the biomechanics of aged teeth. Considering the importance of such aspect, the impact of the age-related dentin deposition on the stress distribution of NCCLs was evaluated by means of finite element analysis. Material and Methods: A 2-dimensional model of a sound maxillary first premolar was created using CAD software. Two tooth geometries (sound, aged) and two lesion shapes (wedge, saucer) were simulated to the model. The mesh was built with 35,000 triangle and square elements of 0.1 mm in length. All tissues were considered isotropic, homogeneous and linear. Occlusal surfaces were loaded with 300 N for simulating normal chewing forces. The stress distribution was analyzed by a color scale and by the maximum principal stress at the cavosurface line angle. Results: The aged models presented lower stress concentration in the overall system in comparison to sound models. The sharp angle of wedge shaped lesions promoted higher stress concentration at the center of cavosurface angle, favoring the lesions progression. Conclusion: Considering the limitations of the current methodology, it is possible to conclude that aged tooth is a more compact structure that can better respond to stress loadings. This protective intrinsic mechanism should be considered when adopting preventive and restorative measures for NCCLs for the elderly. (AU)


Objetivo: A prevalência de lesões cervicais nãocariosas (NCCLs) tem aumentado nos últimos anos, especialmente em idosos. A prevenção e o tratamento bem-sucedidos dessas lesões requerem um entendimento da biomecânica dos dentes envelhecidos. Considerando a importância de tal aspecto, o impacto da deposição de dentina que ocorre com a idade na distribuição de estresse de NCCLs foi avaliado por meio da análise de elementos finitos. Material e Métodos: Um modelo bidimensional de um primeiro pré-molar superior foi criado usando o software CAD. Duas geometrias de dentes (padrão, envelhecido) e duas formas de lesão (cunha, pires) foram simuladas ao modelo. A malha foi construída com 35.000 elementos triangulares e quadrados de 0,1 mm de comprimento. Todos os tecidos foram considerados isotrópicos, homogêneos e lineares. Superfícies oclusais foram carregadas com 300 N para simular forças normais de mastigação. A distribuição das tensões foi analisada por uma escala de cores e pela tensão principal no ângulo da linha cavo-superficial. Resultados: Os modelos envelhecidos apresentaram menor concentração de tensão no sistema geral em comparação aos modelos padrão. O ângulo agudo das lesões em cunha promoveu maior concentração de tensão no centro do ângulo cavo-superficial, favorecendo a progressão das lesões. Conclusão: Considerando as limitações da metodologia atual, é possível concluir que o dente envelhecido é uma estrutura mais compacta que pode responder melhor às cargas de estresse. Este mecanismo intrínseco de proteção deve ser considerado ao adotar medidas preventivas e restaurativas para as NCCLs em idosos. (AU)

ABSTRACT

Most sharp force fatalities are attributed to homicide or suicide, with only a few accidental cases reported to date. Broken glass accounts for most of these accidental fatalities. We herein report an unusual accidental death caused by a broken glass cup. A 21-year-old woman was found dead on the floor of her studio apartment. The studio was a duplex consisting of one room and a bathroom, with a stepped drawer leading to the second floor. She was lying face down with her legs spread apart in a large pool of blood, surrounded by many pieces of broken glass. There was an oblique cut measuring 9 cm in length in the right sternocleidomastoid region just above the right clavicle. The surface of the cut wound showed irregular edges and the internal jugular vein was severed in the depth of the wound. She appeared to have fallen down the steps onto the ground floor and been fatally injured in the neck by a piece of broken glass.

ABSTRACT

La solicitud de estudios de imagen en pacientes con trauma cervical es muy frecuente en la práctica diaria. Esa patología es causa relativamente frecuente de discapacidad en pacientes jóvenes junto con el trauma encéfalo craneano. En un porcentaje no despreciable de los casos, las lesiones traumáticas comprometen la unión cráneo- cervical y en esos pacientes, la morbi-mortalidad es más significativa. La transición entre el cráneo y el raquis se basa en un conjunto de estructuras óseas relacionadas por articulaciones muy móviles y estabilizadas por un grupo de ligamentos y músculos que le brindan al mismo tiempo gran solidez. Para una correcta interpretación de los estudios de imagen de uso corriente en la clínica, es fundamental un sólido conocimiento anatómico de la unión cráneo-cervical y sus componentes. Es el objetivo de esta revisión, sistematizar la anatomía de la unión cráneo-cervical con especial énfasis en sus ligamentos, analizar la fisiología de sus movimientos y el concepto de estabilidad para luego realizar una correlación con tomografía computada multi-detector y resonancia magnética.


The request of imaging techniques in patients with cervical spine trauma is very common in clinical practice. Cervical trauma is a relatively common cause of disability in young patients. In a significant percentage of cases traumatic injuries compromise the cranio-cervical junction with more important morbidity and mortality in this group of patients. The transition between the skull and the spine is based on a set of bony structures, high mobility joints, and stabilization mechanism formed by a group of ligaments and muscles. A solid anatomical knowledge of the cranio-cervical junction and its components is essential for a correct interpretation of current high resolution imaging studies. The goal of this review is highlight the anatomy of the cranio-cervical junction with special emphasis on the ligaments, analyze the biomechanics of their movements and the concept of stability. At last but not leastwe will establish a correlation with multidetector computed tomography and high-resolutionmagnetic resonance imaging.

ABSTRACT

Objetivo: Descrever as alterações nas funções do sistema estomatognático de indivíduos que sofreram queimaduras em face e/ou pescoço. Método: Trata-se de uma revisão sistemática da literatura. A pesquisa foi realizada por meio da Biblioteca Virtual em Saúde (BVS) e busca manual, utilizandose os descritores: queimadura (burn), deglutição (deglutition), mastigação (mastigation), respiração (respiration), fala (speech), sucção (sucking, suction). Foram selecionados artigos publicados entre 2008 e 2018 que descreveram funções estomatognáticas após queimaduras em face e/ou pescoço. Para análise, foram extraídas informações quanto ao número de participantes, sexo, idade, etiologia e grau da queimadura, superfície corporal queimada e características de funções estomatognáticas pós-queimadura. Resultados: Dos 377 artigos identificados nas bases de dados, oito foram selecionados. Além destes, três foram selecionados por meio de busca manual, totalizando a inclusão de 11 artigos. A maioria dos participantes era do sexo masculino, com idade entre dois e 85 anos. Foram descritas queimaduras com superfície corporal queimada entre cinco e 80%, de primeiro a terceiro grau, sendo a maioria queimadura térmica. Seis artigos descreveram alteração na deglutição, cinco relataram alteração na respiração, três na articulação da fala, dois na mastigação e dois referiram comprometimento da mímica facial. Nenhum citou alteração na sucção. Conclusão: As alterações no sistema estomatognático decorrentes de queimaduras em face e/ou pescoço mais descritas na literatura analisada foram relacionadas à deglutição e à respiração, especialmente devido a edema pós-queimadura e restrição de mobilidade causada por hipercicatrização. Alterações na fala, mastigação e mímica facial também foram observadas.


Objective: To describe the changes in the functions of the stomatognathic system of patients that suffered burns on the face and/or neck. Method: This is a systematic review of the literature. The search was performed through the Virtual Health Library (VHL) and manual search, using the descriptors: burn, swallowing, chewing, breathing, talking, sucking, and suction. We included the articles published between 2008 and 2018 that described stomatognathic functions observed after burns of face and/or neck. The number of participants, gender, age, etiology and degree of burn, burned body race and altered stomatognathic functions after burn were extracted by the analyses. Results: Of the 377 articles identified in the databases, 8 were selected. In addition, 3 were selected by manual search, resulting in 11 articles included. The majority of subjects were male, aged between 2 and 85 years. The body burn was performed in 5 and 80%, first of a third degree, being the majority thermal burns. Six articles describe changes in deglutition, five relate breathing impairment, three cited alteration in the articulation of speech, two in chewing and of facial expression. None cited change in sucking. Conclusion: Changes in the stomatognathic system after burn on the face and/or neck, according to the analyzed articles, where most frequently related to swallowing and breathing, especially due to post-burn edema and restriction of mobility due to hypercycatrization. Changes in speech, mastication and facial expression were observed too.

ABSTRACT

The aim of this study was to evaluate the influence of different anterior load type and restorative procedure on stress distribution of maxillary incisors with different noncarious cervical lesions (NCCLs) morphologies. Three-dimensional models of a maxillary incisor were generated. Beyond the sound model (SO), five NCCLs morphologies were simulated: shallow (SH), notched (NO), concave (CO), wedge-haped (WS) and irregular with dual center (IR' and IR"). Composite resin restoration of all the models was simulated (R). Two different anterior loads were applied: 100N on palatine middle third (ML) and 500 N on palatine incisal third (IL). The data were obtained in MPa using the Maximum Principal Stress and Von Mises criteria and the statistical analysis was performed (paired t-test with 95% confidence level). The IL provided higher compressive stress than ML, mainly on WS (-136.3MPa), IR" (-117.5) and NO (-71.1 MPa). The highest tensile stress found within the restored models was on NOR with IL (19,1 MPa). The Von Mises results showed higher stress concentration on non-restored and IL models (p<0.001). The anterior load type and restorative status were determinant factors on stress distribution pattern changes, whereas NCCLs morphologies had little influence in maxillary incisors.


O objetivo deste estudo foi avaliar a influência de diferentes tipos de contatos anteriores e procedimentos restauradores na distribuição de tensões de incisivos superiores com diferentes morfologias de lesões cervicais não-cariosas (NCCLs). Modelos tridimensionais de um incisivo central superior foram gerados. Além do modelo hígido (SO), foram simuladas cinco morfologias de NCCLs: rasas (SH), entalhadas (NO), côncavas (CO), em forma de cunha (WS) e irregulares com centro duplo (IR' e IR''). Restauração com resina composta em todos os modelos foi simulada (R). Dois contatos anteriores diferentes foram aplicadas: 100N no terço médio palatino (ML) e 500N no terço incisal palatino (IL). Os dados foram obtidos em MPa utilizando os critérios de Tensão Máxima Principal e de Von Mises e a análise estatística foi realizada (teste t pareado com nível de significância de 95%). A IL proporcionou maior estresse compressivo que ML, principalmente em WS (-136,3MPa), IR "(-117,5) e NO (-71,1 MPa). A maior tensão de tração encontrada nos modelos restaurados foi na NOR com IL (19,1 MPa). Os resultados de Von Mises mostraram maior concentração de estresse nos modelos não restaurados e IL (p <0,001). O tipo de contato anterior e a presença de restauração foram fatores determinantes nas alterações do padrão de distribuição de estresse, enquanto as morfologias dos NCCLs tiveram pouca influência nos incisivos superiores.

ABSTRACT

Abstract The aim of this study was to verify the prevalence of acts of aggression to the head, face and neck towards victims of Physical Violence against Children and Adolescents (PVCA) who were examined at the National Institute of Legal Medicine and Forensic Sciences Delegation North (INMLCF-DN) in Porto, Portugal. A study was carried out on 2,148 complaints of physical aggression against children and adolescents (0 to less than 18 years old) occurred between 2009 and 2013 and which were retrieved from information about violence held on INMLCF-DN data files. Continuous variables were described and the association between them was verified by Chi-square or Fischer's Exact tests with 5% significance level. Within the 5-year timespan, 1,380 cases were identified with clinical relation with physical aggression. Most subjects evaluated were male adolescents and the most affected body region was the face, to which 747 injuries (24.7%) were recorded, with statistically significant association between sex and region (head and face). Victims in 15-17-year-old age group are more susceptible to violence than those in the 0-14-year-old age range. Dentists routinely examine the face, neck and skull, which make them the most appropriate health professionals to identify cases of aggression early.


Resumo O objetivo deste estudo foi verificar a prevalência de atos de agressão à cabeça, face e pescoço em relação às vítimas de Violência Física contra Crianças e Adolescentes (PVCA) que foram examinadas no Instituto Nacional de Medicina Legal e Delegação de Ciências Forenses Norte (INMLCF -DN) no Porto, Portugal. Um estudo foi realizado em 2.148 queixas de agressão física contra crianças e adolescentes [0 a menores de 18 anos] ocorridas entre 2009 e 2013 e que foram recuperadas de informações sobre violência mantidas em arquivos de dados do INMLCF-DN. Variáveis contínuas foram descritas para verificar a suas correlações foram usados os testes do Chi-Quadrado e o Teste Exato de Fisher em um nível de significância de 5%. Nestes 5 anos, foram detectados 1.380 casos que apresentam nexo clínico com agressão física. As vítimas mais acometidas eram adolescentes do sexo masculino, a região do corpo mais atingida foi a face com 747 das lesões (24,7%) registradas. Há significância estatística no teste do qui-quadrado de Pearson na relação de gênero com a cabeça e o rosto. Dentistas rotineiramente examinam o crânio, rosto e pescoço que os torna os profissionais mais adequados para identificar casos de agressão precoce. Os adolescentes são mais suscetíveis à violência do que as crianças menores de 12 anos.

ABSTRACT

RESUMEN Se estima que al menos del 5 al 10 % de todas las lesiones traumáticas del organismo afectan el cuello. En el 30 % de los casos se afecta alguna estructura importante de esta zona del cuerpo humano. Las estructuras vasculares aparecen lesionadas en el 20 % mientras que las estructuras aerodigestivas en un 10%. Las lesiones de la zona I por diversas razones anatómicas y los órganos que incluye son de difícil manejo. Se presentan dos pacientes con lesiones vasculares de la zona I del cuello. Se realizó una revisión del tratamiento de las lesiones traumáticas del cuello con especial énfasis en las de la zona I. Se abordan diferentes tendencias actuales en el manejo de estos pacientes (AU).


ABSTRACT It is appraised that at least 5 to 10 % of all the organism trauma lesions involve the neck. In 30 % of the cases, any main structure of this zone is hurt. Vascular structures are damaged in 20 % while airway-digestive structures are injured in 10 %. The zone I lesions are difficult to handle because of several anatomic reasons and the organs they include. The cases of two patients with vascular lesions in the neck zone I are presented. A review of the treatment of neck trauma lesions was carried out, making special emphasis on the ones in zone I. Several current tendencies in these patients handling are dealt with (AU).

ABSTRACT

Although penetrating neck trauma (PNT) is uncommon, it is associated with the significant morbidity and mortality. The management of PNT has changed significantly over the past 50 years. A radiological assessment now is a vital part of the management with a traditional surgical exploration. A 22 years old male was assaulted by a screwdriver and sustained multiple penetrating neck injuries. A contrast CT scan revealed a focal pseudoaneurysm in the left common carotid artery bulb. There was no active bleeding or any other vascular injuries and the patient remained haemodynamically stable. In view of these findings, he was initially managed conservatively without an open surgical exploration. However, the patient was noted to have an acute drop in his hemoglobin count overnight post injury and the catheter directed angiography showed active bleeding from the pseudoaneurysm. Surgical exploration 40 hours following the initial injury revealed a penetrating injury through both arterial walls of the left carotid bulb which was repaired with a great saphenous vein patch. A percutaneous drain was inserted in the carotid triangle and a course of intravenous antibiotics for five days was commenced. The patient recovered well with no complications and remained asymptomatic at five months followup.

ABSTRACT

OBJECTIVE: Endotracheal intubation is extremely difficult to perform in patients wearing a cervical collar for a head and neck injury. Therefore, we analyzed actual measurements using the look externally, evaluate 3-3-2, Mallampati score, obstruction, and neck mobility (LEMON) criteria before and after cervical collar application to investigate the causes of a difficult airway. METHODS: This simulation study was performed in 76 healthy volunteers. We measured the mouth opening, modified Mallampati classification, and neck extension before and after cervical collar application. RESULTS: The mean inter-incisor distance significantly decreased from 4.3 to 2.6 cm (P < 0.001). Fifty-seven participants classified as I and II were newly classified as III and IV according to the modified Mallampati classification after cervical collar application (16% to 91%). The angles of neck extension significantly decreased from 44° to 22° after cervical collar application (P < 0.001). Before cervical collar application, our simulations predicted that 14 of 76 participants (18%) would have a difficult airway, whereas after cervical collar application, 76 of 76 (100%) were predicted to have a difficult airway. CONCLUSION: All values for the LEMON criteria (mouth opening, modified Mallampati classification, and neck extension) worsened significantly after cervical collar application. Additionally, a difficult airway was predicted in all participants after cervical collar application.

ABSTRACT

PURPOSE: Trauma is a leading cause of death, even in previously healthy and disease-free individuals, and the mortality rate is very high in neck trauma patients. On the other hand, there have been few studies related to neck injuries. This study examined the characteristics and treatment results of trauma-related neck injuries using the data from Korean National Emergency Department Information System. METHODS: Neck trauma patients were classified using the 6th Korean Standard Disease Classification system. The patients' demographic factors, number of surgeries, and clinical results were investigated. Statistical analysis was conducted using SPSS to evaluate the annual differences in the demographic factors; mortality according to the site of injury and type of surgery; and mechanisms of injury. RESULTS: From 2011 to 2014, 2,458 neck trauma patients were treated in hospitals in South Korea. The number of patients admitted to regional and local emergency medical centers was 883 (35.9%) and 1,502 (61.1%), respectively. No significant annual differences were observed in age, sex ratio, location of treatment center, mortality, and injury site (vascular, tracheal, or esophageal). In addition, no significant differences in the cause of injury, performed surgery (%), and mortality according to the injured organ were observed. CONCLUSION: This study revealed no annual changes in neck injury patients or differences in mortality according to injured organs. This study can be used as a basis for national research on organ-specific injuries, and may help predict the demand for future support projects for the establishment of regional trauma centers.

ABSTRACT

Las lesiones cervicales no cariosas son condiciones patológicas no bacterianas localizadas en el límite amelocementario de los dientes. Los principales biomateriales descritos para el tratamiento restaurador de estas lesiones son: vidrios ionómeros, vidrios ionómeros modificados con resinas, compómeros y resinas compuestas. El objetivo de este protocolo, consiste en establecer los elementos metodológicos de una revisión sistemática que evaluará el comportamiento clínico de restauraciones cervicales realizadas con estos biomateriales. Métodos: El protocolo fue diseñado, y será reportado, en línea con Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P 2015). Se realizará una búsqueda sensible en MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials y ClinicalTrials.gov, sin restricción por lenguaje o publicación, para identificar ensayos controlados aleatorizados que comparen dos o más tratamientos restauradores en lesiones cervicales no cariosas. Los desenlaces a evaluar serán la retención de las restauraciones y caries secundaria, según criterios RYGE/USPHS. Al menos dos investigadores realizarán de manera independiente la selección de los ensayos y la extracción de los datos. El riesgo de sesgo será evaluado utilizando la herramienta recomendada por la colaboración Cochrane. Si es posible, se realizará un metanálisis y los datos serán presentados en tablas de resúmenes de resultados mediante el método Grading of Recommendations Assesment, Development and Evaluation (GRADE). Fortalezas y debilidades: Esta revisión sistemática entregará evidencia actualizada sobre el comportamiento de cuatro biomateriales en el tratamiento de lesiones cervicales no cariosas. La principal limitación proviene de la baja cantidad o deficiencias metodológicas de los estudios primarios. Número de registro (PROSPERO): CRD42017071114.(AU)


Non-carious cervical lesions constitute a group of non-bacterial pathological conditions of the dental structure located at amelocementary junction. The main dental materials that have been described for the restorative treatment of these lesions are: ionomer glass, resin modified ionomer glass, compomers and composite resins. The objective of this protocol, is to establish the methodological elements of a systematic review, that will evaluate the clinical behavior of cervical restorations performed with four dental biomaterials. Methods: The protocol was designed, and will be reported, in line with Preferred Reporting Items for Systematic Reviews and Meta-Analyzes Protocols (PRISMA-P 2015). We will conduct a sensitive search in MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials and ClinicalTrials.gov, without language or publication restrictions, in order to identify randomized controlled trials comparing two or more restorative treatments in non-carious cervical lesions. The evaluated outcomes will be retention of restorations and secondary caries, according to RYGE/USPHS criteria. At least two reviewers will independently select studies and extract data. The risk of bias will be assessed using the tool recommended by the Cochrane Collaboration. If possible, a meta-analysis will be performed and the data will be presented in summary tables of results using the Grading of Recommendations Assesment, Development and Evaluation (GRADE) approach. Strength and Limitations: This systematic review will provide updated evidence on the behavior of four different dental biomaterials in the treatment of non-carious cervical lesions. The main limitation might arise from the low number or methodological limitations of primary studies. Register number (PROSPERO): CRD42017071114.(AU)
